METHOD AND DEVICE FOR DETERMINING PRECODING VECTOR Russian patent published in 2014 - IPC H04B7/05 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication engineering and can be used to precode data in a wireless communication system. To this end, the method includes obtaining first channel state information between a first wireless device and a first base station in a wireless communication system, obtaining first channel gain information, obtaining a first signal power parameter from a second base station indicating signal power generated by the second base station in a second wireless device, and obtaining a first noise power parameter from the second base station indicating noise power generated by the second base station in the first wireless device. The method also includes maximising the overall signal-to-noise ratio parameter to obtain a precoding vector for precoded data to be transmitted to the first wireless device. The overall signal-to-noise ratio parameter depends on the signal-to-noise ratio in the first wireless device and the signal-to-noise ratio in the second wireless device and is based on the first channel state information, first channel gain information, first signal power parameter and first noise power parameter.

EFFECT: high noise-immunity.
